CLOSURE FOR BOTTLES.

Application filed .Tune 7, 1923.

To @ZZ whom t may conce/rfa:

Be it known that I, SAMUEL C. MILLER, a citizen of the United States,residing at Louisville, in the coimty of JeHerson and State of Kentucky,have invented certain new and useful Improvements in Closures forBottles; and I do hereby declare the following to be a full, exact, andclear description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

The present invention relates to improvements in closures for bottlesand has for an object to provide a sealing cap which may be held tightlyagainst rotation.

In spinning these caps which are made of metal foil or light metal, itis impossible to secure a tight fit of the cap upon the stopper. The capis therefore free to turn and its lack of tightness and ability torotate combine to loosen the puller which is associated with the cap.

It is jthe `purpose of the invenltion fto compensate for this deficiencyin the spinning operation and to place the cap under frictional tensionat all times w'hich effectively avoids its rotation and at the same timetightly seals the pull7 in place and prevents the pull from slippingaround the bottle neck.

`With the foregoing and other objects in view the invention will be morefully described hereinafter and pointed out in the appended claims.

In the drawings in which like symbols refer to like parts throughout theseveral views,

Fig. l is a fragmentary side elevation of a bottle neck with a portionof the cap shown in section and with the cap in an initial position Fig.2 is a similar view showing the cap in its final position;

Fig. 3 is a vertical section through a bottle neck and associated parts;and i Fig. i shows a plan view of the cap and compression disk.

Referring more particularly to the drawings, 5 designates the neck of abottle having a bead 6 formed outwardly of its mouth and a depression orannular groove 7 just inwardly of the bead. At 8 is shown the cork orbottom portion of the stopper which fits within the neck of the bottleand at 9 is represented the head of the stopper which is connected withthe cork body and Serial No. 644,026.

is provided with a roughened or corrugated outer surface for conveniencein turning. The head 9 is wider than the cork body to permit such headto rest upon the neck of the bottle or upon the upper edge of the beadG.

The metal cap is shown at l0 and is of substantially cup shape beingadapted to lit about the top, edge and sides of the stopper head 9 andhaving its marginal edge arranged to be driven into the groove 7 by aspinning operation. The cap is in this manner secured over the stopper.Now, it is impossible to spin the edge of the cap in the groove 7 sotightly as to avoid the rotation of the cap upon the bottle neck andthis rotation encourages looseness in the seal and also in the pull.

According to the present invention a disk ll of a material adapted totake a relatively high compression is fitted within the cap l0. The diskl1 normally expands to the condition such as shown in Figs. l and linwhich the expansion takes place axially. The diameter of the expandeddisk ll should accurately conform to the inner diameterI of the cap sothat no space will be left to be filled by the expanding disk when thecap is put under compression. Just prior to spinning the edge of the capinto the groove 7, the cap and the disk beneath it are compresseddownwardly under relatively heavy pressure and the spinning operation isperformed while this pressure is still upon the cap. The disk l1 is incontact throughout with the upper surface of the stopper head 9 andconsequently such disk will be compressed axially at all points throughits surface and it will not be permitted to expand radially due to thetight fit it has in the cap lO. The mass will therefore be compressedlocally at all points and this compression will at all times act in anendeavor to expand in an axial direction and to lift the cap upwardly,but the cap will be restrained by the engagement of the spun edge withthe bead (i. A tight frictional effect will therefore be transmitted tothe cap throughout the entire upper area thereof engaging the upper edgeof the disk and also throughout the contacting walls of the bead G andthe inwardly compressed edge of the cap. This has been found to preventthe rotation and any consequent looseness in the cap.

The pull7 is represented at l2 and it is ing the disk 1l the softmaterial of which,

the disk is made will permit the ribbon to embed itself diametricallyinthe disk and this will serve to prevent the ribbon from turning aboutthe neck of the bottle and it W'ifll also afford a much better hold forthe ribbon when the pull is being operated.

rl^he disk `1l is preferably of lightl cork, although other material maybe found suitable for the purpose.

lt is understood that changes in form, proportion, size'7 and minordetails may be made Within the scope; of the claims without departingfrom' the spirit or sacrificing any of the Y advantages of the presentinvention. l

Wha'tfis claimed is v a 1. In. combination' Withk a bottle neck havingan' annular groove externally thereof, a stopper' having a' portionvextending into the bottleneck and asecond outer portion of greaterdiameter than the inner portion seatedupon the' upper end ofthe bottleneck, a resilient' gasket seated upon theI upper surface of the outerportion of the: stopper,

said gasket having greater resiliency than the said outer portion' ofthe stopper, the outer porti'oir of said stopper being. substantially'fiat andlr continuous toY support thro'ii'ghoutthe resilient gasket,said' gasket' being of: substantially disc` form and of substantiailly'the saune diameter as the outer portion ofthe stopper, a cap'fittedsnugly.

about .the upper and edge portion of said gasket and about the edgeportion of the outer part of the stopper, said cap also overlapping thebottle neck and having an edge portionv spun into the groove, saidgasket being put under compression before the edge is spun into thegroove whereby the spun edge may hold the gasket compressed, and apulling' stripy fitted between said gasket and the cap and embedded bythe cap into" the material of the conipressible gasket When pressure'isk put upon the cap whereby the stri-'p is prevented from pull:- inglongitudinally' or turning in the cap.

2; In combination With a bottle neck havingk an annular grooveexternally thereof, a stopper having a portion extending into the bottleneck and!` avsecond outer portion of greater diameter than the innerportion seated uponl thei upper end of the bottle neck,I a resilientgasket seated upon the` upper surface of the outer portion of therstop-` per and havin-g greater resiilaency than thel said outer portionof the stopper', said gasket being of substantially dise form: and

of substantially the same' diameter as they outer portion of thestopper, and a cap fitted snugly about the upper edge portion of saidgasket andabout the edge portion of the outer part of said stopper',said cap also overlapping the' bottle neck and having an edge portionspun into the groove, said resilient gasket being put under compressionbefore the edge isv spun into they groove, whereby the spunl edge mayhold the' gasket compressed.
